Just like there is air pollution or noise pollution, there is light pollution in the same way and this pollution is increasing continuously. The side effect of this pollution is that things are not visible as they should be. Many citizen scientists spread across the world have presented the report after studying for 12 years. The artificial light at night has started contaminating the natural light. Scientists have told that it is becoming difficult year by year to see the stars at night. artificial light where What’s more, it has become very difficult to see or find stars from there. According to the estimates of scientists, every year some stars are getting hidden in the light pollution. In such a situation, the results of the study also point towards the growing need of the satellite. Now satellites are the only support in seeing the stars or in the investigation of planets and satellites. If the study is done by looking at the stars from the earth, then the real situation will not be clear. There is also a danger that if the stars are not clearly visible from the earth, cultural and health related changes may also occur.Will be there. Stories or songs related to stars will not be common. It will be difficult to understand that future generation, which will be deprived of seeing the starry sky. Very important are the studies of the Globe at Night project published in Kyba et al. low light And the faint stars should also be visible to the human being, but now it is becoming difficult. Scientists have studied how the brightness of the sky has been increasing over time. Analysis of the data for the last twelve years (from 2011 to 2022) shows that the area of the sky affected by artificial lightGlare is increasing worldwide at an alarming average of 10 percent every year, that is, doubling in less than eight years. This enhancement is based on the Defense Meteorological Satellite Program and the Suomi National Polar-Orbiting Satellite Program. Artificial light emissions (two percent annually) are much higher than estimated based on radiation measurements taken by Partnership satellites. Many satellites are also becoming unable to catch and understand the right light. Therefore, in future, there is a need for such satellites, which do not face any kind of problem due to light pollution. by the way keep in mind It is a matter of fact that most of the data that has been published has been taken from Europe and North America. Extensive data and studies are needed. Figures should also emerge from Africa, Asia and Australia. People have to become sensible. Right now people in most cities are very happy to see excessive light, whereas such light is light pollution. Leaves, flowers, fruits and other things appear in a different color in more light. There should be a lot of awareness about the dangers of artificial light at night and light should be used only according to the need.There should be arrangement. Most people also associate artificial lighting with road safety and personal safety, whereas the real solution is something else. Astronomers of the world were quick to realize the pollution that night light could affect their research and moved their observatories away from the bright cities. Wherever we are, we have to understand that without the stars the night has no meaning.
